    ========================================================================
    Note that many games have the regions 0000-0FFF and 1000-1FFF swapped.
    Also, Golden Tee Golf II (V2.2) has most of the addresses in the
    0000-0FFF range swizzled randomly.

    PCB layouts

****************************************************************************

    Summary:

        There are 8 known variants of PCBs for these games. All the PCBs
        have the following features in common:

            68B09 @ 2 MHz for the main CPU
            8k RAM for the main CPU

            68B09 @ 2 MHz for the sound CPU
            2k RAM for the sound CPU
            YM2203C, YM2608B or YM3812 for music
            OKI M6295 for speech (except for YM2608B-based system)

            TMS34061 for the video controller
            ITV4400 custom blitter for rendering
            6-bit RAMDAC for palette, or 2xTMS34070NL (Grudge Match only)
            From 2-8 64k x 4-bit VRAM chips for frame buffers

        An overview of each style PCB is given below:

        Wheel Watcher (Wheel of Fortune)-style
            * Single board

            * 3 VRAM chips for an 8-bit 256x256 video background
              plus a 4-bit 256x256 video foreground layer

        Slick Shot-style
            * Single board
            * YM2203C for music
            * 4 VRAM chips for two 8-bit 256x256 video pages
            * additional Z80 and program ROM for sensor reading

        Hot Shots Tennis-style
            * Single board
            * YM3812 for music

        Rim Rockin' Basketball-style
            * Separate main and sound boards
            * HD63C09 @ 3MHz replaces 68B09 for main CPU
            * YM3812 for music
            * 8 VRAM chips for two 8-bit 512x256 video pages

        Ninja Clowns-style
            * Separate main and sound boards

            * YM3812 for music
            * 8 VRAM chips for two 8-bit 512x256 video pages

        Golden Tee Golf II-style
            * Separate main and sound boards
            * YM3812 for music
            * I haven't see one yet, so I can't provide additional details
